The CEO of one of the top body-armor companies is said to regularly pull a vest from the production line, put it on, and test it by shooting himself. There’s a guy who believes in his product.

As for the guy in this video: the only thing funnier would be if he’d smeared a bunch of chopped-up ghost peppers all over his junk after pulling the trigger. I imagine hilarity (of one kind or another) would have ensued.

I have a young child. Babies are really cute. Some of them become dumb motherfuckers.

Just like the irrational fear filled mom’s and over aggressive dads who raise them by the tenets of economically unbalanced governance and ignorant reactionary media. But hey lets just blame anyone but ourselves for the shit we create, after all why change the habit of a lifetime humans, i mean you have done a bang up job so far.

what a dumbass even if the body armor will stop a bullet it doesn’t really stop the force of the bullet but spreads it over a larger area….and at that range i wouldn’t be too sure about it if it wasn’t one of the military grade ones with the thick ceramic plates

Actually it takes some distance for a bullet to build up momentum. Taking the bullet from 10 or 20 feet away would have been more dangerous.

That’s probably so. I don’t have so much as a passing acquaintance with firearms.

But still I would think that the type of short-range force implied by a typical handgun’s recoil should be enough to shatter your diaphragm at point blank.

you don’t need to be a rocket scientist to understand that a bullet is not a rocket..

Yes you are right there about the diaphragm. The vest stops penetration, however the concussive force could result in organ rupture/damage. Even though the bullet has stopped it has expended all it’s energy at the surface. Though the vest helps somewhat to disperse this force, it is still considerable and the resulting shock waves could very well be lethal. Sometimes even something as weak as a baseball to the chest is sufficient in the right circumstances.

Stop here everyone if you’re only interested in the immediate subject at hand. The rest is not directly pertinent.

Ballistics is a fascinating subject. The more energy that a bullet expends within a body the more damage it does. In this way a small caliber bullet can sometimes do more damage than a large caliber. I stress sometimes, as there are many factors involved.

Say for instance a large fast moving projectile cuts neatly through a body. It’s moving so fast that very little of it’s energy is given up to the target it passes through. Effectively leaving a relatively small passage. The projectile still retains much of it’s energy, which will be expended on whatever else it hits after exiting.

However a small caliber slower moving projectile can expend all of it’s energy within the body. The concussive force is very damaging to surrounding tissue. Also slower projectiles will tend to ricochet off bones and even organs around the body cavity doing much more damage. The bullets potential to pass on it’s momentum energy is actually the most damaging part of a bullet. The bullet itself carves a rather small channel. It’s passing as much of its energy as it can to surrounding tissue that is the killer. Creating concussive waves in the tissue ruptures and destroys it.

That’s the innovation of hollow point ammunition for example. It spreads the inertial energy of the projectile inside the body by effectively peeling the projectile to pieces and spreading it’s energy over a larger area. Small hole going in, large hole coming out. Expending as much energy within the target as possible.

An example to be found in pop culture is when you see someone in a war movie observe when a projectile has gone “clean through”. As in “You’ll be ok it went clean through”, or something to that effect. (I’m doubtful sometimes that the writers are even aware of why this is said, or why it’s supposed to be a good indicator, it’s just something that they’ve heard is said during battles)

When the exit wound is aligned with the entrance wound, also when the exit wound is no larger than the entrance wound, that is “clean through”. (This rule of thumb was discovered early on by medics in warfare with guns) When the exit and entrance wounds are aligned that means the the bullet only traveled a straight path through the body, which means it stayed at relatively high velocity while passing through. This means that there was a minimum of potential energy deposited within the body as it passed through. Often times this is still plenty of energy to be lethal, but if the person is still alive after even a short period of time this could be an indicator that damage to the surrounding tissue was minimized.

Lower velocity projectiles will “wander”, for lack of a better term. Wandering means not taking a direct path, which means more loitering time within the body. The more time the projectile takes to exit the more energy it is expending in the body. The more energy it expends in the body will result in massive damage to the tissue surrounding the path traveled. You wouldn’t need to hit a major organ in order to get a lethal reaction, the projectile merely needs to get close.

“Clean through” is a rule of thumb term which means that the bullet went through while expending the least amount of energy. As opposed to a bullet that penetrates and makes a mess of everything.

Oh dear, look at that I’m babbling on again. Sorry.

Respectfully. That is false, it would not have been more dangerous at 10 to 20 feet. A bullet may in fact still accelerate outside the barrel of a gun. However that distance would be measured in thousandths of an inch. It would be due to a cartridge being improperly loaded with propellant. If a cartridge is loaded with too many grains, or high quality powder or the wrong grain size, the burn will be too long (or it can be too short) resulting in propellant still burning after the projectile has exited the muzzle. For a split second, measured in thousandths of an inch, after the projectile has left the barrel, but before the propellent behind it has dissipated, it might increase in speed for a split second as the propellant expands outside the barrel. There is no appreciable increase in velocity and there are many disadvantages to this happening. This could very well cause the projectile to tumble. Also it will cause a larger explosion, which is a waste of energy, this causes the barrel to move more after a shot, requiring more aiming on the target.

(Large grain powder is for longer barrel guns like rifles. A longer barrel needs a slower burning propellant. But shoots a larger projectile. Small grains for short barrels like pistols. Burns faster, accelerates faster. Smaller projectile. The idea is to have the propellant stop burning just before, but not too much before, the bullet leaves the muzzle. Even though the bullet is free of the barrel’s friction it does not continue to accelerate or “build momentum” once it has left the muzzle. It has done all it’s accelerating in the barrel.)

Muzzle velocity is the velocity of the projectile at the moment it leaves the “muzzle” of the gun, this is the maximum velocity of the projectile. After a projectile leaves a gun it’s speed drops steadily due to resistance with atmosphere.

What got me was while I was watching this I thought “Dude you better get your hand off that slide before you pull the trigger.”
Then I realized he was about to shoot himself point blank in the stomach and I was worried about him
pinching his hand in the slide.
I fear I am desensitized to violence.

Liam_McGonagle

Okay, everyone, let’s just take it down a notch here.

Yeah, yer man’s a dumb*ss, that’s fer sure. But give him SOME credit for not testing the vest by pointing the gun at his head.
